Eject VirtualBox USB always pops up with a specific flash drive

Here goes my issue: Even though I've uninstalled VirtualBox and deleted all VB drivers from the System32 folder and also deleted any references in the Registry, this is what I get when I try to uninstall my 16GB pen drive:

Thank you for your reply JC but I had already done a quick format on the pen drive THRICE. Anyways I went to the root and as I suspected it was empty. I went to the Folder Properties dialog and turned on the display of hidden folders and operating system files. Still no luck. Do you think a complete format will help?

Now you need to narrow down if the problem is associated with a specific USB port (try others) and if the same label is shown if drive G is there or not. That will show if the problem is tied to the specific pen drive, the drive letter or the hardware it is talking to.

If the problem is tied to the pen drive, no matter the drive letter or the hardware port, then you could try the full format. Otherwise, just live with it.

Problem Solved!

Hey just wanted to report that I finally managed to solve this problem today.

I heard about this app called USBDeview recently and I decided to install it on my laptop. Upon opening it, I found a Virtualbox USB listing and decided to purge it. After uninstalling it, I reconnected my flash drive, and lo and behold! The Safely Remove Hardware Menu listed it as "USB Mass Storage Device"! This amazing little utility finally solved my problem!! Thanks again for your help on this JC.
